Placer mining is the mining of alluvial sediments for minerals. This may be through by openpit (also known as opencast mining) or by a variety of forms of tunneling into antique riverbeds. Excavation might be achieved using water pressure (hydraulic mining), layer digging out equipment or tunneling equipment.

The tropical alluvial deposits (placers) are saturated with water. Floating dredges are used to mine alluvial deposits. This type of exploitation is the least expensive method of mining. The operational cost is to mg/m3. Only few paleochannels are more than 50 feet (15 m.) deep.
There''s another form of alluvial mining called artisanal mining. In essence, it is basically the same method employed by gold diggers which involves the screening and straining of mud. In the case of artisanal mining, the extraction process usually takes a longer time as it involves low tech equipment and manual labor. Get details
